Steelmaking Technologies Contributing to Steel Industries –19– NKK TECHNICAL REVIEW (2003) De [Si] –ST siliconization. The reaction vessel is a ladle type, and the hot metal is vigorously stirred by injecting lime through a submerged lance. This method dramatically improved the oxygen efficiency for desiliconization over the conven

However, the current reclaiming ratio of waste steel in China is still low due to lack of advanced slag treatment equipment and technology. Utilization as sinter material Steel slag with CaO content above 50% can be used as sinter ore fluxing agent, partially replacing the commercial lime.

Converting is a type of metallurgical smelting that includes several processes; the most commercially important form is the treatment of molten metal sulfides to produce crude metal and slag, as in the case of copper and nickel converting. A nowuncommon form is batch treatment of pig iron to produce steel by the Bessemer process. The vessel used was called the Bessemer converter.

and treatment method using a rotary cooler as the main equipment. Studies on slag treatment process Two types of slag stem from iron and steelmaking processes: blast furnace and steelmaking slags. Various methods for granulating blast furnace slag using water were developed since the 1970s, and its use as blast furnace cement rapidly ...

Mineralogy of primary phases in slags and mattes from the Tsumeb smelter (Namibia) 5.

In 1996 the treatment equipment was installed in line of converter no. 1 of the steel shop of Thyssen Krupp Stahl AG, Duisburg, since then it has worked successfully. The free lime content of all slags determined produced by this treatment show amounts <1% by weight. Thus, they do not show any volume increase.

Steel Steel Openhearth steelmaking: Though it has been almost completely replaced by BOF and EAF steelmaking in many highly industrialized countries, the open hearth nevertheless accounts for about onesixth of all steel produced worldwide. The openhearth furnace (OHF) uses the heat of combustion of gaseous or liquid fuels to convert a charge of scrap and liquid blastfurnace iron to ...

melting furnaces, pressure pour furnaces and magnesium treatment vessels with minimal to no adverse effects on refractory linings. Slag Formation: The formation of slag in the melting of ferrous metals in the foundry is inevitable. The composition of slag varies with the type of melting process used and the type of iron or steel being melted.

Extraction of tin consists of three parts, tin ore concentration, smelting and refining. Cassiterite is the main source of tin ore, with specific gravity of /cm 3, density larger than most of, 90% of tin concentrate is mainly obtained from cassiterite through gravity separation.

producing a metallic alloy (referred to as black copper) and a slag phase. black The copper can be refined in different ways, whereof one is by using it as a secondary feed material for input to PeirceSmith converter. Consequently the load of minor s elements to the converter can be expected to increase with an increased treatment of escrap.

Converter slag In the same way as aircooled blast furnace slag, converter slag is cooled slowly by natural cooling and water spray in a cooling yard. It is then processed and used for various iron and steel slag (converter) applications. Approximately 110 kg of slag is generated for each ton of converter steel. Electric arc furnace slag

PDF | Several methods of reprocessing metallurgical (blast furnace) slag into materials for the building industry, based on melting aggregates with submerged combustion, were developed and tested.
